    The solution of the equations, by either analytical or numerical means, describes how the biological system behaves either over time or at equilibrium. There are many different types of equations and the type of behavior that can occur is dependent on both the model and the equations used. The model often makes assumptions about the system.

    en.wikipedia.org/wiki/Selection_coefficient

    Selection coefficient, usually denoted by the letter s, is a measure used in population genetics to quantify the relative fitness of a genotype compared to other genotypes. . Selection coefficients are central to the quantitative description of evolution, since fitness differences determine the change in genotype frequencies attributable to selecti

    The proper way of applying the abstract mathematics of the theorem to actual biology has been a matter of some debate, however, it is a true theorem. [3] It states: "The rate of increase in fitness of any organism at any time is equal to its genetic variance in fitness at that time." [4] Or in more modern terminology:

    The Lincoln Index is merely an estimate. For example, the species in a given area could tend to be either very common or very rare, or tend to be either very hard or very easy to see. [3] Then it would be likely that both observers would find a large share of the common species, and that both observers would miss a large share of the rare ones.
